AWS set to develop mobile cloud services?

According to a recent job posting, Amazon appears to be creating native mobile apps for the Amazon Web Services (AWS) business unit. The job listing is for the Palo Alto, CA office. The entire development team will be located there.

Amazon has a long track record of creating native mobile apps (Kindle Reader, Amazon MP3 Player app, Amazon Video On Demand, etc.). However, this is the first sign that AWS itself is focusing on mobile services.

What do you think they will offer in terms of new services for mobile app developers?
